HTML5 Websocket within Webworker
javascript, web-worker, websocket
Solution
You must listen for the onopen websocket event before sending your first message.
socket.onopen = function(){
// send some message
};
Problem
I've managed to get websockets working inside a webworker using Chrome, but only for receiving data. When I try to send data I get a DOM Exception, has anyone managed to send data? This is what I have for my web worker. ``` self.addEventListener('message', function(e) { var data = e.data; switch (data.cmd) { case 'init': self.postMessage("Initialising Web Workers..."); testWS(); break; default: self.postMessage('Unknown command: ' + data.msg); }; }, false); function testWS() { var connectionAddr = "ws://localhost:8003"; var socket = new WebSocket(connectionAddr); socket.onmessage = function(event) { self.postMessage('Websocket : ' + event.data); }; socket.onclose = function(event) { }; function send(message) { socket.send(message); } send("hello"); //Here is where the exception is thrown } ```
